PAINT-CAN STIFRING ATTACHMENT.

Specification of Letters Patent. Patented lIar. 28, 1916.

Application filed November17, 1915. Serial No. 61,918.

To all whom it may concern:

Be it known that I, JOHN WV. CAIRNS, a citizen of the United States,residing in the city and county of San Francisco and State ofCalifornia, have invented new and useful Improvements in Paint-CanStirring Attachments, of which the following is a specification.

My invention relates to an attachment to paint and like cans containingheavy semifluid substances which it may be desirable to agitate in orderto prevent the heavier portions from separating and settling to thebottom of the can.

It consists ofa transversely disposed and journaled shaft havingradiating arms projecting and fitting the curvature of the can bottomand detachable exterior means by which the shaft may be oscillated orturned so that the contained materials may be kept in a properly mixedcondition.

It also consists in details of construction, which will be more fullyexplained by reference to the accompanying drawings, in which Figure 1is a vertical section of a can, showing the interior and my invention.Fig. 2 is a perspective view of the stirring arms. Fig. 3 is a view ofthe'operating handle.

As shown, A is a can or receptacle adapted to contain paint or othersubstance, the ingredients of which are liable to settle and separatewhen the container remains long in one position. Preferably my can isformed cylindrical and with a bottom which is concave interiorly, as at2.

3 is a shaft extending across the can and journaled in its sides, as at4 near the bottom.

5 are arms or blades projecting from the shaft. In the present casethese arms are flat, tapering and paddle-shaped, and may be made ofvarying length so as to conform to the segmental or curved form of thebottom of the can, near to which their ends approach.

To allow the cans to be conveniently packed for shipment, the journals 4are formed within the can and the outer ends Copies of this patent maybe obtained for five cents each. by addressing the "Commissioner ofPatents.

'One of the journaled ends of the shaft 3 may be formed with a notch 7or equivalent means to receive the tongue 8 of the arm 9. This isapplicable when the protecting plate 6 has been removed and by turningthe shaft, the arms will agitate and stir the mass and keep it in propercondition for use.

The coverof the can 10 is removable to expose the interior for use whenrequired and the contents may be stirred and kept in condition for use,as described.

Having thus described my invention, what I claim and desire to secure byLetters Patent is 1. In combination with a can having a fiat lower endand a concave bottom'and having alined openings formed in its oppositesides, a shaft having reduced ends turnable in said openings and havingradial paddles thereon, one of said reduced shaft ends having a slottherein and each of said shaft ends terminating substantially flush'withthe respective sides of the can, a key having a part engageable in' saidshaft slot, and relatively thin metal plates secured to the can sidesand extending over the shaft ends to'normally conceal the latter and toenable exposure of the slotted end of the shaft upon removal of thecorresponding plate.

2. In combination with a can having alined openings formed in itsopposite sides, a shaft having its ends turnable in said openings, saidshaft having paddles thereon and having each of its ends extendingsubstantially flush with the respective sides of the can, one of saidshaft ends having a keyreceiving slot, and a relatively thin metal platesecured to the can side and disposed over said slotted shaft end, saidplate being removable so as to expose said slot.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
